Function
EAIP
Error Acknowledge-
ment In Process
This bit is part of the error handling.
Encoder recognizes error.
Encoder sets SE bit in G1_ZSW1
and error code in G1_XIST2.
IO Controller recognizes the error and sets the
SEA bit in G1_STW1.
Encoder sets the EAIP bit.
IO Controller clears the SEA bit in G1_STW1.
PA
Preset
Acknowledge
Bit is set by encoder after the preset operation has
been successfully completed. Encoder resets the bit
when PR bit is reset by IO Controller.
TAA
Transfer Absolute
Acknowledge
The bit is set as soon as G1_XIST2 supplies valid
position data and will be reset when the SE or PSA
bit is set.
PSA
Parking Sensor
Active
Acknowledgement reaction on PS bit of G1_STW1
SE
Sensor Error
The bit is set as soon as the encoder has identified
an error. Error code is presented in G1_XIST2. Bit
TAA is reset.
Error codes in G1_XIST2:
0x0001 position error
0x0F01 invalid command in G1_STW1
0x0F02 failure of Master Sign-of-Life
